If you want to use a specific set of collectors, you can define them in the ExecStart section of the service. You can see the details about the set in the README-file. By default a set of collectors is activated. Collectors are used to gather information about the system. Copy the following information in the service file, save it and exit Nano: ħ. Create the following file by opening it in Nano: sudo nano /etc/systemd/system/node_rviceĦ. To run Node Exporter automatically on each boot, a Systemd service file is required. Remove the leftover files of Node Exporter, as they are not needed any longer: rm -rf node_exporter-0.16.0. node_exporter-0.16.0.linux-amd64ĥ. Sudo chown node_exporter:node_exporter /usr/local/bin/node_exporterĤ. Copy the binary file into the directory /usr/local/bin and set the ownership to the user you have created in step previously: sudo cp node_exporter-0.16.0.linux-amd64/node_exporter /usr/local/bin This will create a directory node_exporter-0.16.0.linux-amd64, containing the executable, a readme and license file: tar xvf node_exporter-0.16.0.ģ. Download the latest version of Node Exporter: wget Ģ. Sudo chown prometheus:prometheus /var/lib/prometheus Downloading and Installing Node ExporterĪs your Prometheus is only capable of collecting metrics, we want to extend its capabilities by adding Node Exporter, a tool that collects information about the system including CPU, disk, and memory usage and exposes them for scraping.ġ. Set the ownership of these directories to our prometheus user, to make sure that Prometheus can access to these folders: sudo chown prometheus:prometheus /etc/prometheus Create the folders required to store the binaries of Prometheus and its configuration files: sudo mkdir /etc/prometheusģ. Sudo useradd -no-create-home -shell /bin/false node_exporterĢ. sudo useradd -no-create-home -shell /usr/sbin/nologin prometheus To achieve this, we use the parameter -no-create-home which skips the creation of a home directory and disable the shell with -shell /usr/sbin/nologin. To run Prometheus safely on our server, we have to create a user for Prometheus and Node Exporter without the possibility to log in. In this tutorial, we use an instance running on Ubuntu Xenial (16.04).ġ. Downloading and Installing Node Exporter.There are five steps to use Prometheus with Grafana: The software stores all its data in a time series database and offers a multi-dimensional data-model and a powerful query language to generate reports of the monitored resources. Prometheus is a flexible monitoring solution that is in development since 2012. You have an account and are logged into.This tutorial explains how to use a Prometheus Monitoring server with Grafana Dashboard.
